To all whom it may concern:

"Be it known that 1, DAVID EDWARD PAYNE, a citizen of the United States, residing at Magnolia, in the county of Rock and State of Minnesota, have invented certain new and useful Improvements in Post--l: :[ole-Boring Machines; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in post hole boring machines, and the principal object of the invention is to provide a device which is adapted for boring and removing the earth from post holes.

Another object of the invention is to provide a device having an endless conveyer connected thereto for lifting the earth after the same has been brought'up by the auger.

A still furtherobject of the invention is to provide a feeding means by which the device may be readily lowered into the ground. Still another object of the invention is to provide a device which is adapted to be folded so as to occupy a. minimum amount of space when not in use. i p

2 With these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which Figure 1 is a perspective view of this improved post hole boring machine;

Fig. 2 is a front end elevation of Fig. 1;

Fig. 3 is a vertical sectionalview through Fig. 1; l

Fig. 4 is a horizontal sectional view through the vertical frame and the carriage;

Fig. 5 is a detail perspective view of one of the slides.

Fig. 6 is an enlarged fragmentary vertical sectional view through one of the standards illustrating the slides in place;

Fig. 7 is an enlarged detail interior view of. the ratchet wheel; and

Fig. 8 is a sectional view through Fig. 7..

Referring to the drawings the numeral 1 designates as an entirety, the base of the device having connected thereto at one end the vertical frame designated generically by the numeral 2. The base 1 comprises a pair of side-bars 3 connected by cross bars 4: while the frame 2 comprises the vertical side bars 5 connected at their upper ends by a head 6.

The lower ends of the side bars 5 are hingedly connected as at 7 to the ends of the side bars 3 of the frame 1 so that the device may be readily folded. The vertical side bars 5 of the frame 2 are provided with longitudinal grooves 8 and secured to the forward faces of said bars are longitudinally extending metal studs 9 which partially overlie the grooves as illustrated in Fig. 4 to act as retaining flanges by which the carriage slides are held against movement out of proper position. Secured to said side bars and extending inwardly therefrom, are rack bars 10 which cooperate with the feed pinions of the carriage in lowering the same into the ground. Suitable adjustable brace arms are pivotally attached near the forward end of the base 1 and their opposite ends are slidably connected to the frame 2 near its upper end so, that relative adjustment of the frame with the base may be readily had.

The carriage above referred to is designated generically by the numeral 11 and comprises the vertical side bars 12 connected at their upper ends by a head 13 while the lower ends of said bars are connected by a cross bar 14. Suitable journal bearings 15 are attached to the front faces of the side bars 12 and form supports for the shaft on which the driving mechanism of the augers and conveyers is mounted. The bar 14 of the. carriage 11 is provided with a central bearing through which the shaft 17 extends, the lower end of which carries the augers 18 while the upper end of said shaft is provided with a beveled pinion 19 for meshing engagement with a beveled pinion 20 carried on the shaft16. Mounted on the shaft 16 at opposite sides of the beveled: pinion 19, are sprockets 21 for operating the conveyer chains and mounted outwardly toward the ends ofthe shaft adjacent the sprockets 21 are pinions 22 for meshing engagement with the rack bars 10. These pinions act as feed pinions for lowering the device when the same is in operation. In order to brace the vertical shaft 17 against accidental move- "ment, a suitable bracket 23 is secured to the Extending downwardly from the under side of the bar 14: in spaced parallel relation, are parallel Supporting arms 28 the lower ends of which have rotatably mounted therein the trunnions 29 of a central bearing 30 through which the lower end of the shaft 17 extends. Sprockets 31 are rotatably mounted on the trunnions 29 and form guides for the lower ends of the conveyer chains 32 on which suitable conveyer buckets 33 are secured. It will thus be seen that as the earth is carried up by the auger 18 the conveyer buckets 33 will gather the same and carry it well above the auger dumping the earth on the rear side of the machine.

In order to support the carriage in place, suitable slides designated generically by the numeral'34: are provided and each comprlses a pair of parallel plates 35 having their ends bent inwardly as at 36 and then outwardly forming attaching flanges 37. Rollers 38 are rotatably mounted between the plates 35 and are adapted to engage the bottom wall of the groove 8 while the flanges 37 are apertured to receive suitable attaching means by which the slides are secured to the carriage.

It will be apparent from the foregoing the drawings, and the carriage is then raised to its upper limit of travel whereupon the anger is put in place and upon turning the crank it will be seen that the auger w1ll be revolved and the carriage simultaneously lowered. As soon as the auger Stcl'tS to work it will be seen that the earth will be carried upwardly until it is engaged by the buckets 33 which will carry the same upwardly and away from the hole being drilled, thus keeping the auger free and preventing the earth from interfering with the roper operation of the device. 7

I hile in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood frame with the upright frame; supports ex- Copies of this patent may be obtained for iorizontal tending from the horizontal frame to the upright frame to permit of the upright frame assuming an inclined position with respect to the horizontal frame; a carriage slidably "mounted on said frame; an auger carried by the carriage; a' conveyer carried by the carriage and in proximity to the auger; and, means to simultaneously operate the conveyer and auger.

2. In a post hole drilling machine, a horizontally arranged frame; an upright frame arranged on the horizontal frame near one end thereof; hinges connecting the first named frame with the upright frame; supports extending from one end of the .horizontal frame to the upright frame and having an elongated opening therein; set screws arranged on the side of the vertical frame and extending throughthe elongated openmg of said support topermit of the ad ustment of the upright frame in an inclined position with respect to the horizontal frame; a carriage slidably mounted on said upright frame; an auger carried by the carr1age; a conveyer carried by the carriage and in proximity to the auger; and means to simultaneously operate the conveyer and anger. V a 3. In a post hole drilling machine, a horizontally arranged frame; an upright frame arranged on one end of the horizontal frame; hinges connecting the first named frame with the upright frame near one end thereof; supports extending from, the sides of the horizontal frame and near the opposite end thereof to said upright frame, each support having an elongated opening near a one end thereof; a set screw arranged on the side of the upright frame and extending through said elongated opening to permit of said upright frame assuming different angular positions with respect to the horizontal frame; a carriage slidably mounted on said upright frame; an auger carried by the carriage, a conveyer carried by the carriage and in proximity to the auger; and means to simultaneously operate the conveyer and auger. i

In testimony whereof I afiix my signature in presence of two witnesses.
